SURGICAL SPLINT.

SPECIFICATION forming part of Letters Patent No. 718,339, dated January13, 1903. Application filed April 22, 1902. Serial No. 104,208. (Nomodel.)

To ctZZ whom. it 7771607.]0072067711.

Be it known that I, ANDREW W. GRAHAM, a citizen of the United States,residing at Bradford, in the county of McKean and State of Pennsylvania,have invented new and usefulImprovements in Surgical Splints,of whichthe following is a specification.

My invention relates to improvements in surgical splints, and pertainsmore particuzo larly to hinged splints.

The object of my invention is to provide a splint which is adapted tofold from the center, and by so arranging the arms upon which the saidmembers of the splint proper are :5 carried the splint is adapted toopen and close exactly as a human-joint.

Another object of my invention is to provide a splint that is rigidlyheld in the adjusted position and cannot be moved without a key ordevice adapted for that purpose.

A still further object of my invention is to provide a cheap, simple,and effective splint to accomplish the above results.

In the accompanying drawings, Figure 1 is a top plan view. Fig. 2 is abottom plan view. Fig. 3 is a side view, partly broken away. Fig. 4 is asectional View taken on line so a; of Fig. 8. Fig. 5 is a sectional viewon line y 'y of Fig. 3.

Referring now to the drawings, A A represent the two sections of mysplint, which are preferably provided with the concaved surfaces a a,adapted to fit the curvature of the arm or leg to which it is applied.As

clearly shown, the said sections are spaced apart, and one section isadapted to be applied above and the other below the fractured joint. Theedges of said section A have embedded therein and secured, by means ofscrews, rivets, or other suitable fastenings, the upwardly-curved arms Band B, while the section A has secured thereto in a like manner the arms0 and C, and the upper ends of said arms are provided with offsets c 5and 0, While the arms B and B are provided arm B, and is provided at itsouter end with an opening 6, and swiveled within said openin g is alaterally-extending eye F,Which is provided with a verticalscrew-threaded opening f. The arm C is also provided with an opening Gdirectly below the eye F, and swiveled therein is a laterally-extendingeye H, provided with the vertical opening 72., and said opening isscrew-threaded'in the opposite direction to that of the eye F. Passingthrough said eyes is a screw-threaded member I, which has its upper endJ screw-threaded in one direction and its lower end J screw-threaded inthe opposite direction. said screw-threaded portion is provided with I asquared portion K, which is adapted to enter a key or instrument adaptedfor that purpose. By turning the said screw-threaded rod the eyesthrough which it passes are thus drawn together or forced apart, andthus throw the two sections of the splint at different angles or throwthem in a straight line. The eyes being pivotally mounted in the arms,

it will be readily seen that when the screwthreaded bar is turned andthe arms drawn together the said eyes will turn, and thus prevent thespringing of the bar or breaking .of the threads carried thereby.

Having thus described rnyinvention, What I claim, and desire to secureby Letters Patent, is-

l. A surgical splint, comprising two mem' bers pivoted together, movableeyes carried by said members, and ascrew-threaded memher passing throughsaid eyes, substantially as described. l

2. A surgical splint comprising two members, oppositely-extending armscarried by said members and pivoted together, an ex- 0 tended membercarried by one of said arms, and an adjustable connection between saidextended member and the opposite member substantially as described.

3. A surgical splint comprising two mem- 5 bers, armscarried by saidmembers and pivoted together, a movable eye carried'by one of said armsbeyond its pivotal connection, a second movable eye carried by the armcarried by the opposite member, and a rod passing through said eyes andhaving its ends oppositely screw-threaded.

The outer end of the 65 I 6. A surgical splint comprising two members,upwardly-extending arms carried by said members and pivoted together,swiveled eyes carried by said members, and a rod havingoppositely-screw-threaded ends passing through said eyes, substantiallyas described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

ANDREW W. GRAHAM.
